The present invention relates to cooking stoves and ranges, and more particularly to Combination stoves or ranges using bot-h iuid and solid fuel for cooking, baking and heating.

It is the primary object of the invention to provide a combination range `having in addition to the usual provisions for cooking and baking with gas and heating and cooking by coal, Wood or othersolidD fuel, a built-in-gas heater which may be employed for heating the room in .which the range is located.

Another-object of the invention .is the pro'-V vision vof sucha combination range vhaving a novel combination and arrangement of the gas heater with reference to the coal or solid'heater and the baking oven.

A further object is the provision 'of a novel and improved radiant gas `heater intended especially for use in cooking stoves vand ranges.

The invention also has among its other ob jects the provision of a novel assemblage of th component elements of the gas heater, provision for the flow o f air to and from the gas. heater, and provision for the discharge of products of combustion.

With the foregoing' and other objects'in view, which wll be apparent as the descripi tion proceeds, the invention resides in the construction andgarrangement of parts, as

hereinafter described and claimed, it being understood that changes can be m'ade within the scope of what is claimed, wit-hout departing from the spirit of the inventlon.

The invention is illustrated vin the accompanying drawings, whereln-'- Figure 1 ,1s a perspectiveview of acombinationrange embodying the invention.

Fig. `2 is a vertical'section on the line 2 2 Fig. 3 isa verticalsection on the line 3`3 of Fig. 1,with the griddle and oven door removed.

Fig. 4 is a front view of the range,partly in section onthe line 4 4 of Figf2, with the oven door removed. l

Figs. 5 and 6 are horizontal sections taken on the respective lines'v and 6-6 of The cooking, stove or range illustratedis of conventional form in general respects,4

' and the embodiment of the invention as illustrated and described is to be takenas typical, inasmuch as the invention may be incorpo flues 24 and 26 into the top 'flue 21.

to the bac rated in stoves and ranges of different styles.

The range comprises a body 10 having the baking oven 11 therein withf a door 12 at the `front of the range to give access to 'the oven,

and below the' bot-tom 13 of the oven isdisosed a gas burner 14 forheating the oven. he body 10 has a 's ace .or chamber 15 v above the oven in whic the gas burners 16 for cooking are located, and the cooking top of the body 10 includes the griddles 17 above the chamber '15, the 'burners 16 being located under said griddle and being supplied, with gas, as usual, by a gas supply pipe 18 through the control valves 1'8. The body 10 has a vertical partition 19 therein between the end or side walls ofthe body, and divid ing or sepa-rating the oven 11, and burner chamber 15 from the solid fueland gas heaters. 'Said body has the horizontal partitions 20 andg 20 forming the top of the oven and bottom of the chamber 15, respectively,` with a to oven flue 21- between said partitions 20. an 20. The oven 11 has side walls or partitions 22 and 23 which are located adjacent to but spaced from the partition 19 and corresponding end or sidewall ofthe body, respectively, to'provide vertical ues 24 at the opposite sides of the oven.

The back wall 25 of the ovenis alsospaced from the back wall ofthe body 10, as'seen in Fig. 3, to provide'a rear verticalue 26.

The oven bottom 13 being spaced above the bottom of the body provides a bottom flue 27 below the oven in which the burner14 is `located, and thebottom of the body has an airff' inlet opening- 27 below the'burner 14, with@ shield or gua-rd 27 below'said opening so' that the air must iowalong the bottom of the body before passing up4 throughj-tne opening 27. The products of combustion from the burner 14 pass along the oven bottom 13, andlthence upwardly through the back wall ofthe body has A,the outlet openings 28 and 29 communicating with the flue 21 and chamber 15, respectively, and witha flue or pipe connecting member 30 secured wall of the body 10 for the connection of the stove pipe or flue that carries The 0H the products 'of combustion from. the

- oven and chamber 15. It will be apparent that products .of combustion from the burners v16 b'elowuthegriddle 17 v may pass through the'opening 29 into the member 80,...

and that the products of combustion rising into the ,lues 24, 26 and 21 ofthe oven may l pass through the opening 28 into the meml ber 30.

As shown in thedrawin s, the solid f uel and gas heaters are locate at the left-side of the' oven, but it will be apparent that the construction' may be reversed with the solid fueland gas heaters at the right slde of the oven, so that said fuel and gas heaters may be located at either side or the back of the oven. located between the partition 19 and the corresponding end or side wall/31 of the body 10. A horizontal partition 32 is disposed between the partition 19 and wall 31 above the body and extends forwardly from the back wall of the body,V and a vertical par tition 33 extends upwardly from the 'forward end of the partition 32. The forward end of the partition 32 and the partition 33 are spaced rearwardly' from the front wall of the body, and said partitions 32 and 33 the door 36 in order that the grate may bel separate the solid fuel and gas heaters. shaking or other suitable bottom grate 34 1s' located above the partition 32'between the partition 33 and back wall of the body, and the space 35 between the grate 34 and partition 32 provides an ash pit in which an ash Y pan (notshown) maybe disposed as usual for catching the ashesv that pass down through the grate 34. nThe wall 31 vof. the lbody has. an ash door 36, which, as shown, is

' hinged to swing downwardly, in order that the ashes may be readily removed. As shown, the grate 34 has a stem or shank 37 projecting out through the wall 31 above vibrated to shake down the ashes. Above the grate 34 is the firebox 38 in whichcoal, wood, coke or other solid fuel may be burned, and said irebox may be lined as usual. The top vof the body has the removable lids 39 above the firebox, and the back wall of the body has the outlet-opening 40 for the discharge of the products of combustion from the firebox into the pipe or Hue attaching member 41 to which the stove pipe or flue is connected 'as usual. A damper 42 is mounted in the member 41 to check the draft when desired. As seen in Fig. 2, a forwardly inclined partition 43 extends from the u per endI of the partition33. and front end o the firebox 38 to the upper edge of the front wall of the body above the space between said front wall'and partition 33. By this arrangement the 'upper portion of the lirebox is extended forwardly ton the front wall of the body, and it will-be noted that the front lid 39 extends over the partition 43. The coal or other solid fuel is deposited in the firebox 38 by removing the 1-ids139, and any coal or solid fuel -that is dropped down through the front opening will slide downv the partition or plate 43 into the. rebox. said partition 43 'providing a chute to direct the fuel rearwardly into the firebox proper.

The solid fuel and gas heaters are` Coming to the gas heater, it is located in front of the solid fuel heater, in the space between the lartition 33 and front wall ofy includes the upright radiants 46 composed of suitable refractory material andha'ving suitable openin The radiants 4.6 are located behind the opening 45 and are exposed through said opening,

for the outlet of the flames andv products o combustion from said radiants.

and when heated will radiate heat outwardly 1 or forwardly through the opening 45.

The lower ends of the radiant-s 46, which are open, are seated on a shelf or horizontal plate 47 disposed in rear of the lower edge of the opening 45, with the lower ends ofthe 'radiante disposed over a battery of Bunsen burner tubes 48. As shown, the tubes 48 are integral with the shelf 47 and a horizontal bar 49 below the shelf 47, said tubes 48 being'- cast in one unit.

zontal as pipe 51 that extends through the flue 27 elow the oven bottom 15. The pipe 51 may be secured in' the collar 50 by means of set screws or the like. The pipe- 51 has The ends ofthe bar 49 have depending collars receiving amhori-l upwardly extending discharge nipples 52 y projecting upwardly into the ltubes 48 to diS- charge the gas upwardly into said tubes, a'nd the lower ends of the tubes are open so as to admit air to mix with the gas .The gas discharges upwardly from the tubes 48 into the `radiants 46, and screens 53 or otherdiffusers are disposed across the upper ends of the tubes 48. The radiants 46 aredisposed side by side between the partition A19 and wall 31, and their front walls are of lattice construction to provi-de forwardl direzed openings through which the ames an 55 of the gas supply ypipe 18, and the wall 31 carries a capplate 56 to receive and encloseV ythe end of the pipe 51 which protrudes through the wall 31, as seen in Fig.4.

An upright back vplate 57 for the radiante 46 is provided, said radiants being disposedl in front of said plate, and saidvplate being spaced in ,front of thepartition 33. The plate 57 is secured to the partition 33 by means of bolts4 58 or 'other securing elements, with spacers 59 between said plate. and partition lto space them apart. The plate 57 has forheat may'pass. The pipe 51 is eon, nected by a control valve 54 with a branch wardly extending e'ars- 61 at its lower edge on x.

which-the shelf 47 is secured by means of bolts or other securing'l` elements, thereby sup# porting the shelf'47 from' the plate 57 'which "is in turn supported from the partition 33.

horizontal forwardly extending ribs 60 against which the radiants 46 bear, thereby spacing said radiants slightly from the plate 57, vwith a clearance between them for the flow-of air and products of combustion upwardly between the radiants and plate 57.

A deflecting plate 62 is disposed behind the upper portion of the opening 45, and is loosely'connected at its upper edge with the` front plate 44 atthe upper edge of the opening 45 by means of a bolt 63 or other securing element. Said plate 63 extends downwardly and rearwardly at an angle from the upper edge ofthe opening 45 with its lower edge extending across the radiants near the upper ends thereof, thereby holding the radiants against the 'back plate 57 Further,- more, air rising from the radiants will be deflected forwardly intovthe room by the plate 62, so that said plate serves'the double function of holding the radiants in place and deflecting the heated air forwardly. A sill plate 64 is disposed across the lower edge of the opening 45 and its rear edge extends across the radiants 46 at the lower ends theres of, to hold said radiants on the shelf 47. Said-plate 64 also provides a `neat finish for the lower end of the opening 45. The `plate 64 has projecting end portions 65 to engage behind the front plate 44. Upright corner pieces 66 are secured in the corners between the front plate 44 and partition 19 and wall 31, and the portions engage behind the corner pieces 66, as seen in Fig. 5. This will hold the plate 64 in place, and one piece 66 has a lug 67 to project over the corresponding portion 6-5 so as toy hold the plate 64 down. lnorder to remove said plate it is necessary to swing the opposite end of the plate upwardly so as to withdraw the plate from under the lug 67 and outwardly through Athe opening 45. When the plate 64.

is removed the radiants 46 mav be raised slightly so as to lift them loff the' shelf 47 and tubes 48 and the radiants may then be removed by swinging their lower ends forwardly' and then withdrawing the upper ends Aof the radiants from between4 the plates -57 and 62. This enables the .radiants to be taken out for cleaning, repair or replacement.

A rearwardly extending baffle 68 is secured to the front plate 44 below the gas burners `of the gas heater, and the front plate 44 has air vinlet apertures 69 in front of the gas burner between the plate 64 and baffle. Said front 44 also has vair outlet apertures 70 "above the opening 45.0r between the plates 43 and 62. The apertures 69 and 70 near Ithrough the openings, 70.

thelower and upper` ends, respectivelyapf the plate 44 are forvthe admission and4 charge of air fiowing to and from the gas` heater. The chamber or flue 471 below the partition 32 is open at the bottom in rear of thebaifle 68, so that air may flow upwaradly into said chamber or flue 71 and thence up wardly through the flue or space 72 between the partition 33 and plate 57,.so as to be heated by contact with the plate 57. From the flue 72 the heated air rises into the space 73 above the radiants between the plate 62 and partition 33 and below the plate 43, and.,

the heated air passes forwardly through the openings 70 into the room. llt will also be noted that when the solid fuel heater is used, air passing upwardly through the flue 72 and space 73 will be heated by the partition 33 and plate 43, thereby providing for the circulation of air in the room when heated by either solid fuel or gas.

The partition 19 has an opening 74 establishing communication between the space 73 above the radiants 46 and the flue 21. Thus, products of combustion rising from the radiants or gas burner into the space 7 3 may be drawn off through the flue 21, thus preventing at least some of the products of combustion from passing into the room. lf desired, the opening 74 may be in the partition 33 so that the products of combustion are discharged into the firebox to be drawn ofi' with the products of combustion of the solid fuel. The gas fumes are thus drawn olf by' the u'sual draft provisions ofthe range or stove. The present structure provides for a threeway combination, namely, v(1) a gas range with a cooking top and a baking oven, (2) a heater using coal or other solid fuel, and (3) a radiant gas heater. Thus, either solid fuel or gas may be used for heating, or, if desired, both heaters 'may be used vsimultaneously, although this may not ordinarily be necessary. The gas heater occupies the space in front of the solid fuel heater, within the the fireboX overhan'ging` the gas heater, it

lou

voutline of the body 10, with an extension of serves as a chute for the solid fuel deliveredI into the lirebox,.and also serves to deflect heated air rising'in the space 7,3 forwardly The air rising through the flue or space 72 will be heated from either the solid fuel -or` gas heater. When the radiant gas heater is used, heat is radiated outwardly or forwardly through the opening or window- 45 directly into the room, and air also flows upwardly -behind the back plate 57 of the, radiants through.

the flue or space 72 so as to provide for a circulation of a1r in the room.
